SECTION 1 : INTRODUCTION
1.1 Preliminary
Comments
and
Safety
Precautions
This technical document is intended to cover most
aspects associated with the installation, application,
operation and maintenance of the ATS-01
Automatic Transfer Switch Controller. It is provided
as a guide for authorized and qualified personnel
application of the ATS-01 Automatic Transfer Switch
Controller.
3. Intelligence control unit to constantly monitor the
condition of the power sources and thus provide
the intelligence necessary for the switch and
related circuit operation.
This manual deals with the third basic element of
the automatic transfer switch, the required
intelligence automatic control module. All the
Automatic Transfer Switch functions were
performed by a door mounted logic panel ATS-01
control unit. The ATS-01 logic panel brings
intelligence,
supervisory
and
programmable
capabilities to automatic transfer switch equipment.
1.2 Overview
1.3 Product Overview
Transfer switches are used to protect critical
electrical loads against loss of power. The load's
normal power source is backed up by a standby
(emergency) power source. A transfer switch is
connected to both the normal and emergency
sources and supplies the load with power from one
of these two sources. In the event that power is lost
from the normal source, the transfer switch transfers
the load to the standby source. Once normal power
is restored, the load was transferred back to the
normal power source.
The ATS-01 Automatic Transfer Switch control
module is an intelligence, comprehensive,
multi-function, microprocessor based automatic
transfer switch controller. It is a compact panel
mounted device designed to replace traditional relay
and solid state logic panels and meet the needs of
markets worldwide.
The ATS-01 controller provides an unmatched
degree of programmed flexibility to address the
needs of most switches system. It can be
programmed for 3Ø, 1Ø and 1Ø 3W system
operation. ( Refer to program line 2 )
When using the ATS-01 module in automatic
transfer switch equipment, the switch's intelligence
system initiates the transfer when normal power
falls below or over a preset voltage or frequency. If
the emergency source is a standby generator, the
transfer switch initiates generator starting and
transfers to the standby source when sufficient
generator voltage and frequency is available. When
normal power is restored, the transfer switch
automatically transfers back and initiates engine
shutdown after a preset engine cooling down time
delay.
● Monitor Normal and Standby source over and
under frequencies.
An automatic transfer switch consists of three basic
elements:
● Permit customer programming display real time
information.
1. Main contacts to connect and disconnect the load
to the source of power.
● Permit customer programming cyclic mode or fix
mode display for 3 phase voltages and frequency.
( Refer to program line 29 )
2. A transfer mechanism to affect the transfer of the
main contacts from one source to another source.
● Permit system testing the transfer switch
with/without load from front panel. ( Refer to
program line 4 )
The ATS-01 controller provides the necessary
intelligence to insure that the switch operates
properly through a series of programmed sensing
and timing functions. The ATS-01 controller will :
● Monitor Normal and Standby source over and
under voltages.
● Store customer / factory established parameters
in memory without losing.

1.4 Functions / Features
The primary function of ATS-01 controller is to
accurately monitor power sources and provide the
necessary intelligence to operate a transfer switch
in an appropriate and timely manner.
1.4.1 Operational Simplicity
From installation to programming to usage, the
ATS-01 controller was designed with operational
simplicity in mind. The ATS-01 controller operates
with system voltage from 160 VAC to 260 VAC at 50
or 60 Hz. The user-friendly front panel interface
simplifies routine operation, programming and
setting adjustments.
TDNE provides a time delay when transferring the
Normal source to the Standby source. It ensures
stability of the Standby source. Timing begins when
the Standby Source becomes available. ( Refer to
program line 6 )
Adjustable TDNE range : 0 ~ 60 (0 ~ 300 sec)
Feature 2 : Time Delay Engine Start (TDES)
TDES delays the initiation of the engine start circuit
in order to override momentary power outages or
voltage fluctuations of the Normal source. The
TDES timer shall start when the Normal source
becomes unavailable. If the Normal source
becomes available while timing, the TDES timer will
reset. The ATS-01 controller can perform the time
delay engine start function without control power for
30 seconds. ( Refer to program line 7 )
Adjustable TDES range : 0 ~ 6 (0 ~ 30 sec)
Feature 3 : Time Delay Emergency to
Normal (TDEN)
TDEN delays the transfer from the Standby source
to the Normal Source to permit stabilization of the
Normal Source before retransfer is made. Timing
begins when the Normal Source becomes available.
( Refer to program line 5 )
Adjustable TDEN range : 0 ~ 60 (0 ~ 300 sec)
1.4.2 Standard Features
A variety of programmable features are available to
meet a wide variety of application requirements.
Individual features or feature combinations provide
the intelligence required tailoring switches to
individual needs. The features can be programmed
by customer via friendly setting procedure,
depending upon customer requirements. The
specific variable set points associated with standard
and factory activated features are stored in a
nonvolatile memory. Activated feature set points are
available for customer adjustment.
Feature 4 : Time Delay Engine Cool-down
(TDEC)
TDEC permits the generator to continue to run
unloaded after retransfer to the Normal Source has
occurred. Timing begins when the transfer to normal
has been completed. ( Refer to program line 8 )
Adjustable TDEC range : 0 ~ 60 (0 ~ 300 sec)

or Transfer fail alarm output.)
Feature 7 : Plant Exerciser
This feature provides for automatic test operation of
the generator. The interval is fixed at once per week
with a specific test day and time. The test period is
also programmable by customer setting. The
ATS-01 control unit permit customer plant engine
test with / without load on a preset period. ( Refer to
program line 21,22,23,25,26,27 & 28 )
Feature 11 : Fail Alarm On Display
Feature 8 : Pre-transfer Signal Output
FAIL on the front panel of the ATS-01 indicates that
a transfer was initiated but never completed. This
can point toward a defective motor, transfer
mechanism or the wrong programming for line
3.When the transfers fail alarm occurred, the ATS
will hold this position until the OFF button is pressed
to reset alarm signal.
When the auxiliary contactor was set to be a
pre-transfer signal output. The ATS-01 controller will
provide a pre-transfer signal to elevator controller
before transfer the load from one source to another
source with a preset time delay. The pre-transfer
return to normal state after the transfer is complete.
( Refer to program line 30 & 31 )
NOTE! Normally, MCCB type ATS need longer
running time to complete there cycle, so if line 3 is
set wrong the switch stops before completing it’s
cycle and the ATS-01 will give you a FAIL transfer
Alarm. Make sure the line 3 setting is set right
before checking any other parts of the ATS
mechanism.
Adjustable range : 1 ~ 99 sec.
Feature 9 : Pre-exerciser Signal Output
When the auxiliary contactor was set to be a
pre-exerciser signal output. The ATS-01 controller
will provide a pre-transfer signal output before
exerciser the engine. It is an advance warring to
avoid person damaged before the generator auto
start itself. ( Refer to program line 30 & 32 )
Adjustable range : 1 ~ 99 sec.

4.3 Engine Test Mode
The ATS-01 is provided with a test pushbutton that
simulates a loss of normal source. Pushing the
TEST key on the front of panel, the ATS-01 will run
in engine test mode. The TDES and TDNE
programmed time delays will be performed as part
of the Test. There are two test modes:
Begin to start programming mode, set the ATS-01on
off mode, push the button “ increase ( ▲ ) &
decrease (▼) ” on the front panel for 4 seconds. The
word “ Ver 1.0 ” will appear on the front display
window for 2 seconds. This number indicates the
version of the software.
● With load engine test.
You are now ready to start a line by line
programming sequence. To advance to the next line,
push the OFF button on the front panel. To change
each line’s programming parameters, press the
increase ( ▲) and decrease ( ▼) buttons. When
pressing and releasing the increase ( ▲ ) or
decrease (▼) key the displayed parameter can be
increased or decreased by one. The Increase (▲)
or decrease (▼) pushbutton will continue to scroll if
it is pressed and not released.
● Without load engine test. ( The TDNE time delay
will not be performed )
When the user terminated the engine test mode by
press the AUTO pushbutton, then the controller will
return to automatic mode. When normal power is
available, the transfer switch automatically transfers
back from standby source to normal source and
initiates engine shutdown after a preset engine
cooling down time delay.
When the user terminated the engine test mode by
press the OFF pushbutton, the ATS will keeps the
present status and the ATS-01 controller initiates
engine shutdown immediately without cooling down
time delay and returns to off mode.
Always push the “ OFF ” button to advance to next
programming line or until the word “ END ” appears
on the screen. To immediately end the programming
mode, you can simply push the “ OFF ” button for 4
seconds at any time. Then the word “ END ” on the
display window indicates the end of the
programming mode.
4.4 Off Mode
The off mode of the ATS-01 controller will disable all
the transferred and protected functions, and all the
status LEDs will be turned off in this mode. The real
time clock will be showed on the front display
window.
In the event that power is lost from the normal
source, the ATS-01 controller will not start the
engine and the ATS can’t transfer the load to the
standby source automatically.
Should you make an error or desire to return to
factory settings, stay in programming mode and
simultaneously press all 3 buttons : increase (▲),
decrease (▼) and OFF for 4 seconds. The ATS-01
controller will now automatically program itself to
factory settings and the word “ Au.Po ” will appear
on the display window. ( See line by line
programming table for ATS-01 factory settings. )
When in program mode, pushing the off pushbutton
allows the user to change the program line table and
set the selected parameter using decrease (▼) or
increase (▲) button.
4.5 Programming Mode
